Goodbye puppers

[Sorry for the picture quality]
A while ago a stray dog jumped over our fence into the back garden and got my dog pregnant. When she had the puppies I promised myself I wouldn't get too attached to them because I knew I couldn't keep them.
The time came when they were old enough to leave their mother and I had to give them away. It was one of the most sad and hard things I've ever had to do.(I mean look at their faces)
